19. Blueberries
One of the best sources of vitamin C is the blueberry. But what makes blueberries such a deserving entry on this list, is the fact that they don’t just contain vitamin C (which is a potent antioxidant) but also a whole host of other antioxidants.
Antioxidants of course work to combat free radicals in your diet. These are agents that will collide with the cell walls and cause damage when they do. Over time, they can get all the way through and damage the DNA, potentially causing the formation of cancer.
This is one of the reasons to seek out vitamin C and all the foods on this list. But it’s even more reason to seek out blueberries, which are fantastic at combating this effect on multiple fronts!
